PENGARUH LARUTAN FIXER TERHADAP KUALITAS PEWARNAAN BIOPIGMEN RUMPUT LAUT Eucheuma sp. SEBAGAI PENGGANTI PEWARNA SINTETIS PADA TEKSTIL
Abstract: Seaweed Eucheuma sp.
is one of the natural resources of Indonesia. Seaweed many processed in dry
form after going through a drying process or processed into food ready for
consumption. Seaweed is no longer just eaten or used to direct treatment, but
can be processed into jelly, Algin, carrageenan (carrageenan) and furselaran
(furcellaran) which is an important raw material in the food industry, pharmaceuticals,
cosmetics and so on. This plant has an important economic value in various
industries such as pharmaceutical, cosmetics, food, textile and paper
industries.
This study aims to determine the Fixer solution of Tawas, Poly Aluminium
Chloride and Kapur Tohor most effective at biopigmen Eucheuma sp. instead of
synthetic dyes in textile and determine the best concentration of the solution
Fixer Tawas, Poly Aluminium Chloride and Tohor in deciding the color biopigmen
Eucheuma sp. instead of synthetic dyes in textiles. This study uses a
randomized block design (RAK). This research was conducted by observing and
comparing the effect Fixer solution between Tawas, Poly Aluminium Chloride and
Kapur Tohor against staining quality biopigmen seaweed Eucheuma sp. instead of
synthetic dyes in textiles.
Organoleptic test results showed fixation material Poly Aluminium
Chloride able to maintain better color than the color produced by the fixation
Tawas and Kapur Tohor. Poly Aluminium Chloride fixation material produces a
bright brown color, Tawas brown, reddish brown Tohor. The test results of color
fastness to rubbing cloth (dry) indicates that the color fastness of the
strongest to the weakest sequentially generated from Tawas fixation materials,
lime Tohor, Poly Aluminium Chloride, while the test fastness to washing soap
and desecration of white cloth from the strongest to The weakest is Poly Aluminium
Chloride, Kapur Tohor and Tawas.
